File upload directory paths are not intuitive

[John.K]

Issue

There are currently three places where 'paths' can be defined in the CiviCRM settings:
Admin > System Settings >
  Directories
  Resource URLs
  Cleanup Caches and Update Paths

The path labels are also not intuitive. For example, Contact images are uploaded into the 'Custom files' directory, not the 'Images' directory. (Although this is explained in the help text beneath the field).

There is currently no explanation of the relationship between the paths specified in the 'Directories' and 'Resource URLs' pages.

Proposed changes

Reduce the number of pages paths can be set on: merge it all in to one page if possible?

Reduce / rename the number of directories: ie: if images are not uploaded in the 'Images' directory, then what should that actually be called?

Restructure the directories: perhaps we could specify a 'base' uploaded file directory, and then specify certain folders to be used for certain types of file. Eg:

Base file directory: sites/default/files/civicrm/custom/
- Images subdirectory: images/
- 'Premium' images subdirectory: images/premiums/
- Temporary files : tmp/ (Although these shouldn't probably be elsewhere?)

Remove hard-coded 'image/' directory definition in 'contact/imagefile.php' - this could be configured above.
